In this case, lawmakers are trying to pass the initiative as-is, while immediately amending it with compromise language hammered out between supporters, police organizations and prosecutors.

If the Senate approves the compromise and the governor signs it, any opponents have 90 days to file a challenge. If not, the measure becomes law.

The initiative would remove the so-called malice clause in Washington state law, which would make it easier to prosecute officers in the most extreme cases. Proving malice in Washington state is known to be difficult.

In the eleventh hour of the legislative session, lawmakers convinced police unions and initiative backers to come to the table and come up with a compromise.

"We want to be part of the solution. We want to start a constructive conversation with the community and believe our engagement will help to reduce the polarization," said Steve Strachan, Washington Association of Sheriffs and Police Chiefs Executive Director.

"We appreciate the input law enforcement has had in the process of drafting this bill to strengthen and clarify its intent and effect," said Heather Villaneuva with De-Escalate Washington.
